It carries 24 square inches of zinc inside a clear PVC housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy a pool needs an anode\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWater, dissolved salts and dissimilar metals make a battery. Left alone, that galvanic action eats at heat exchangers, ladder anchors, light rings and any other metal in the system. A zinc anode gives the reaction something easier to consume, so the zinc wastes away and the expensive metal does not.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe clear housing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAnodes only work while there is anode left, which is exactly the thing most owners never check. The Technode housing is clear PVC, so the remaining zinc can be seen from the equipment pad without breaking into the plumbing. A weatherproof installation sticker is supplied to record the date and keep the service interval honest.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it goes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the in-line version, made to sit in a tee in the pipe run. Perma-Cast also builds a Technode that fits a metal filter or heater core, so pick the one that matches where you want the protection.\u003c\/p\u003e","brand":"Perma-Cast","offers":[{"title":"Default Title","offer_id":48634533478612,"sku":"PER-45-1001","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_3ca68948-9845-42a8-9038-45f9cedb1f44.png?v=1788833988","url":"https:\/\/www.activepoolsupply.com\/products\/permacast-tn-100-technode-in-line-anode-for-tee-24-sq-inch-zinc","provider":"Active Pool Supply","version":"1.0","type":"link"}
